' ROTARY PUM P.

SPECIFICATION forming part of Letters Patent No. 228,344, dated June 1,1880. Application filed October 20, 1879.

To all whom it may concern:

Be it known that I, J OHN HALLNER, of Saunders, in the county ofSaunders and State of Nebraska, have invented certain new and usefulImprovements in Rotary Pumps; and 1 do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanyingdrawings, which form apart of this specification, and in which- Figure l is a front or faceview of a rotary pump embodying my improvements, the face plate havingbeen removed to show the arran gement of the operating parts. Fig. 2 isa similar view with the face-plate and valve-wheel removed. Fig. 3 is aplan of the inner side of the Fig. 4 is an axial section of the same.Fig. 5 is an inside View of one of the two circular disks which, whenunited, compose the valve-wheel. Fig. 6 is a side view of one oftheslidin g double-headed valves detached from the valve-wheel. Fig. 7is an end or edge view of the same. Fig. 7 a is a sectional view of oneof the valve-heads. Fig. 8 is an inverted view of the guide-shoe bywhich the valves or gates are operated; and Fig. 9 is a perspective viewof one of the triple cranks for operating the pump when it is immersedor inserted into the well or reservoir from which the water is to bedrawn.

Similar letters of reference indicate corresponding parts in all thefigures.

Thisinvention relates to rotary pumps audit consists in an improvedconstruction and combination of the operating parts, as hereinafterdescribed, and particularly pointed out in the claims, having for itsobject to produce a pump that can be easily and evenly operated withoutjerks or spurts, is absolutely air and water tight, capable of raisingwater to a great height or distance, and, withal, requires but littlepower proportionate to the work accomplished to operate it.

In the two sheets of drawings hereto annexed, A represents thecylindrical pump box or casing, which is provided with theinduction-pipea and eduction-pipe or outlet 1). Pivoted in one side of the casing A isa segment, B, the upper end of which impinges upon a block, d, which issunk into a recess in the edge or rim of the casin g and atlixed uponthe end of a spring, 6, which works in a segmental slot in the rim ofthe casing back of the hinged segment B.

The cylindrical casing A has a central journal-box, f, on one side ofwhich, opposite to the segment B, is another smaller segment, 0, whichis pivoted at one end upon a pin projecting inwardly from thecylinder-head, close up against its journal-box f, and recessed on itsunder side to receive a spring, h, (see Fig. 8,) which bears against apin in the cylinderhead, so as to impel or force the segment 0 outwardlyfrom the central journal-box /l The large hinged segment, B, I call thepackingsegment or gainer, and the small pivoted segment, 0, I call theguide-shoe. The gainerspring 6 impinges upon a set-screw, 12, insertedthrough the rim of the casing A, by means of which its tension relativeto the block d and segment B may be adjusted from the outside Withoutdisturbing or removing any part of the machine.

The rotary valve or piston wheel is made in two parallel circularsections, D D, which, bolted together, form the complete wheel or disk.The part D, which faces the inner head of easing A, with its pivotedsegments B O, has an annular flange, i, slotted at right angles to makeroom for the valves or pistons, and is provided with a central hub orjournal, f, which fits into the central box, f, of easing A. Theadjoining part, D, has a central hub, is, which extends out through theface-plate of easing A, as shown in Fig. 4. of the drawings, and isprovided with a crank or pulley for operating it.

Both parts D D are slotted diametrically at right angles, and are soplaced together that the slots of one register with those of the other,thus forming two diametrical channels, H, in the body of the wheel,crossing each other at right angles. lnto these channels are insertedthe double-headed pistons E E, the heads E E of which have projectingshoulders or flanges m, which bear against the spring guide-shoe O, ashereinafter described.

The flanges on may be provided with friction-rollers, as shown at a inFig. (3, or with springs which work against the curved back of the shoeas the wheel with its pistons is rotated, and each of the piston-headsis recessed to receive spring or any other suitable packing, so as toform a water-tight joint with the heads and rim of the cylindricalcasing A.

For the use of deep wells, or where it is desired to lift the water to aconsiderable height, the pump may be immersed in the well and operatedby means of the attachment shown in Figs. 1 and 9. This consists of twoshafts, F F, provided with triple cranks, G G G, the cranks of the uppershaft being connected with those of the lower by rods or cables H of anysuitable length. The uppermost shaft, F, has a pulley or crank foroperating it, and both the shafts are arranged within a suitable boxing.By this arrangement the pump may be placed sufficiently close to thewater to be operated easily, and yet lift acolumn of water to anydesired height, as the length of the rods or wires H H H which connectthe two triple cranks is immaterial.

From the foregoing description, taken in connectionwith the drawings,the operation of my improved rotary pump will be readily understood.

The hinged packing-segment or gainer B, operated by the spring 6 andblock d, will impinge closely upon the valves or pistons as these rotateand take up wear, while the block at will prevent water from enteringthe space behind said block and the segment occupied by the spring. Thepistons, being made with double heads E E', greatly simplifies theoperation of the pivoted guide-shoe (J, upon which the pistons rideduring the revolution of disk D 1), while the spring h, by forcing theend of the segmental shoe down against the flanged heads, insures aperfect and uniform reciprocating motion of the pistons, and compensatesfor wear of these as well as of the shoe.

An additional and very important advantage resulting from theconstruction and arrangement of the yielding segments B G, as described,is that the pump may be used for pumping muddy or gritty water, or watercon- .tainin g small pieces of rock, gravel, and other impurities,without injury to its parts, which makes it desirable for use in mines,coal-pits, the flushing of old wells, and similar purposes.

The diameter of the pump being comparatively small, a large volume ofwater may be lifted with proportionately little power, wheth-' er thisis applied direct to the shaft of the valve-wheel or indirectly by meansof the crank attachment with its connecting-rods.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. In a rotary pump, the diskcomposed of the parts D D, provided with diametrical right-angledchannels l l, registering with each other, slotted flange i, and hubs fk, substantially as and for the purpose herein shown and described.

2. The combination, with the diametricallychanneled disk D D, havingslotted flange i, of the double-headed valves or pistons E E, set atright angles to and sliding centrally upon each other within theirrespective channels ll in disk D D, substantially as and for the purposeherein shown and described.

3. The combination, with the cylindrical casing A and radial valves orpistons E of a rotary pump, of the pivoted segment B, block d, spring 0,and set-screw a, substantially as and for the purpose set forth.

4. The combination, with the cylindrical casing A, having centraljournal-box, f, of the pivoted segmental guide-shoeC, provided with thespring h, arranged and operating substantially as and for the purposeherein shown and specified.

6. The shafts F F, provided each with triple cranks G G G, set atdifferent angles, in combination with the parallel connecting rods orwires H H H, and hub of a rotary pump, substantially as and for thepurpose herein described.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.

JOHN HALLNER.
